Definitions

  • the invention relates to a guide device for guiding a furniture part, in particular a sliding door or folding sliding door, comprising at least one guide rail and at least one chassis which can be connected to the furniture part and can travel on the at least one guide rail.
  • the at least one chassis has at least one carrying roller mounted about a first axis of rotation for supporting the weight of the furniture part, and at least one supporting roller for laterally guiding the furniture part.
  • the at least one supporting roller is mounted rotatably about a second axis of rotation aligned transverse to the first axis of rotation.
  • the invention furthermore relates to a piece of furniture with at least one furniture part, in particular a sliding door or folding sliding door, a furniture carcass, and at least one such guide device.
  • the invention furthermore relates to a method for guiding at least one furniture part, in particular a sliding door or folding sliding door, relative to a furniture carcass by means of at least one such guide device.
  • a deformation of the supporting rollers can occur. This has the result that the guide device can no longer move smoothly or a rattling of the supporting rollers occurs.
  • Such a deformation is also called flattening and is caused by a force permanently acting on the supporting rollers while they are not being moved.
  • the object of the invention is to improve a guide device to the effect that a flattening of the supporting rollers is prevented or at least reduced.
  • a further object of the invention is to provide a piece of furniture with an improved guide device.
  • a further object of the invention is to provide a method using an improved guide device.
  • At least one support device separate from the at least one supporting roller is provided which is formed to relieve the pressure on the at least one supporting roller in at least one end position of the at least one guide rail against a transverse force acting laterally, i.e. substantially parallel to the first axis of rotation.
  • the at least one support device has at least a first part and a second part which are movable relative to each other.
  • the first part and the second part are coupled to each other in a first position in order to relieve the pressure on the at least one supporting roller against the transverse force, and the first part and the second part are decoupled from each other at least in a second position.
  • One of the at least two parts of the at least one support device can be connected in a movement-coupled manner to the at least one chassis, and/or the other of the at least two parts of the at least one support device can be arranged fixed, preferably is connected to the at least one guide rail.
  • Such a design can make a more stable construction possible, as only one part of the support device can be moved, while the second part can be arranged fixed. The likelihood of damage to the components can thus be reduced, as the component which can be arranged fixed has no room to move.
  • the at least one support device can have at least one ramp, and preferably the at least one ramp is aligned substantially parallel to the second axis of rotation of the at least one supporting roller, and/or the at least one ramp is aligned at an angle to a longitudinal direction of the at least one guide rail.
  • parallel is meant here that the axis of rotation and the plane of the ramp do not have a common point of intersection.
  • the ramp is at an angle to a longitudinal direction of the guide rail when it forms an acute angle with the latter.
  • the ramp can serve to guide the support device and thus make the process for relieving the pressure on the at least one supporting roller in an end position of the guide rail easier.
  • At least one carrier can be aligned substantially parallel to the second axis of rotation, on which the furniture part can be mounted, preferably via at least one hinge, and/or at least two guide rails are provided which are arranged substantially transverse to each other.
  • a carrier which is aligned substantially parallel to the second axis of rotation, makes it possible to connect two guide devices in a movement-coupled manner. As a result, a better and more stable guiding of the furniture part can be achieved. Above all, in the case of lateral loads, a tilting of the furniture part can thereby be prevented.
  • a carrier can act as a connection means between the individual rollers and can thus simultaneously act as a chassis.
  • the furniture part it is also possible for the furniture part to be mounted on two guide rails standing transverse to each other. A movement around the corner is thereby possible.
  • the folding sliding door it is possible for the folding sliding door to always be located outside the space between the two guide rails during a corresponding movement.
  • the freedom of movement of the furniture part can be increased through the use of two guide rails.
  • the use of a second guide rail can make it possible to move the furniture part in a direction transverse to the first guide rail; as a result the lateral loading of the first guide rail can increase.
  • the relieving of the pressure on the supporting roller in end positions thereby becomes all the more important in order to prevent a flattening of the supporting rollers.
  • the at least one support device has at least one rolling body, preferably the at least one rolling body is mounted rotatably about a third axis of rotation aligned parallel to the second axis of rotation of the at least one supporting roller, and/or is mounted on the at least one chassis via at least one needle roller bearing, and/or consists of steel at least in regions.
  • a rolling body as part of the support device can improve the relieving of the pressure on the supporting roller in an end position of the guide rail. In an end position, a coupling-in can be made easier through the round shape of the rolling body.
  • the rolling bearings are mounted rotatably about an axis of rotation parallel to the second axis of rotation. Such a positioning makes an optimum relieving of the pressure on the supporting roller possible, as the rolling bearings can be aligned parallel to the at least one supporting roller.
  • steel can be used for the rolling body at least in regions.
  • other hard, non-brittle materials are also conceivable. The deformation of such materials is negligible even in the case of lengthy loads. As a result, such materials are ideal for a permanent relieving of the pressure on the supporting rollers.
  • the at least one support device can have at least one sliding body.
  • a sliding body can also be used in order to guarantee the relieving of the pressure on the supporting rollers in an end position of the guide rail.
  • Such a sliding body can be used as an alternative or complement to a rolling body.
  • the sliding body can serve the support device as a guide during the pressure-relieving process, in order to gradually restrict the room available to the guide device to move in the region of the end position and to gradually reduce the loading of the supporting rollers in this region until the coupled-in position is reached.
  • a contact between the at least one supporting roller and the at least one guide rail in the at least one end position of the at least one guide rail can be removed by the at least one support device.
  • a flattening of the supporting roller can thereby be ruled out, as a lateral load no longer acts on the supporting roller in this end position.
  • the at least one guide rail consists of aluminum at least in regions, and/or a lateral surface of the at least one supporting roller consists of plastic, and/or the at least one support device has at least one steel part which can be arranged fixed.
  • the guide rail can be advantageous to make the guide rail out of aluminum at least in regions.
  • it can be advantageous if it consists of plastic. It is also conceivable for only the outer shell of the supporting roller to consist of plastic.
  • the support device it can be advantageous if at least one part of the support device which can be arranged fixed consists of steel, in order to prevent wear and deformation of the support device. A consistent relieving of the pressure on the supporting roller can thereby be guaranteed.
